LUCIUS P. YALE AND HERBERT E. BEAGAN, OF CHICAGO, ILLINOIS.

END-DUMPING DEVICE.

Specification of Letters Patent.

Patented March 2, 1909.

Application filed. July 18, 1908. Serial No. 444,280.

To all whom it may concern:

Be it known that we, LUoIUs P. YALE and HERBERT E. REAGAN, both citizens of the United States, and both residing at Chicago, inthe county of Cook and State of Illinois, have invented certain, new and useful Improvements in End-Dumping Devices, of which the following is a specification.

- At present, when it is desired to make an embankment or rade for railroads and other construction wor i, it is customary to erect a superstructure for the purpose of permittin the filling material to be transported to and dum ed 1n proper position. This improved end umping device is constructed especially with a view to eliminating such superstructure, the construction of which involves considerable time, labor and expense.

The invention consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a top or plan view of this improved end dum ing device; Fig. 2 a similar view, the movab le turntable and upper trackway being removed; Fig. 3 a

transverse section, taken on line 33 of Fig.

1; Fig. 4 a top or plan view showing the turntable in turned position; and Fig. 5 an outer end view of the end dumping device shown in Fig. 1.

This improved end dumping device consists essentially of a fixed section 6 havin railroad tracks 7, which are secured as usua upon ties or sleepers 8. A movable platform section 9, having companion end and intermediate cross supporting beams 10 and outer and inner longitudinally channeled beams 11 and 12 res ectively carry, as shown in Fig. 2, flan ed w eels 13, traveling upon the car trac s 7 of the fixed track section 6. An outer circular trackway 14 is formed upon the upper side of the lower movable platform section, the same being adapted to engage the flanged wheels 15 of a revoluble turn table structure 16.

As shown, this turn table structure carries the railroad tracks 17 and 18, which are fastened upon the transverse frame su ports 19, the outer supporting beams 20 o the turn table,-as shown, being of channeled formation, serving to journal and carry the wheels 15 which travel upon the tracks 14 of the lower platform section. Adjacent to and outside of the railroad tracks 17 and 18 upon the revoluble turn table structure are projecting guard beams 22 for distributing the material from the tiltable dump car bodies during the filling in operation. The revoluble turn table structure travels about the central axis 23, it being understood that the same may be actuated by the cable 24 passing about the annular periphery of the revoluble turn table structure or otherwise, power being supplied to the cables from an engine actuating the swinging drum 25. The trackwork 26 is laid in elevated position over the fixed lower track structure for the purpose of enabling the dump cars to travel onto the tracks of the revoluble turn table structure for dumping the material.

In use, the dump cars are run out upon the upper inclined trackway 26 and are there positioned upon the revoluble turn table structure. The turn table is then usually moved 90 degrees and the filling material Within the cars dumped in desired position. One of the chief advantages of this construction is that it enables the dump cars to be run onto the turntable structure from one of the tracks, and, the turn table having been moved 90 degrees and the cars dumped, the same may be run off onto the other track when the turn table has been turned another 90 degrees, so as to bring the empty cars into register with the return track. This method enables the work to proceed continuously, the loaded cars running in on one track and the empty cars traveling upon the return track.

When sufficient material has been deposited, the lower permanent track section is laid upon the completed embankment, the upper movable platform traveling upon the rails; and when the movable platform is in extreme advanced position upon the rails, the end dumping device is ready to receive the dump cars which travel upon the upper inclined track section, as heretofore described.

This method of filling in uneven surfaces and for elevating track or road structure is especially advantageous in that it enables the work to more readily and economically progross, for the reason that the erection of superstructures is eliminated.

What we claim as new and desire to secure by Letters Patent is:

1. In an end dumping device, a lower section of track, a movable platform traveling upon the lower section of track carrying a turntable, and means for moving the turntable, substantially as described.

2. In an end dumping device, a lower section of track, a movable platform traveling upon the lower section of track and having a circular trackway, a turntable having its wheels traveling upon the circular trackway, means for moving the turntable, and an upper section of track having its outer ends in register with tracks on the turntable, substantially as described.

3. In an end dumping device, a lower section of track, a movable platform traveling upon the lower section of track, a circular trackway upon the movable platform, a revoluble turntable having outer channel beams serving to journal wheels traveling upon the circular trackway, a centrally dise posed axis for the revoluble turntable, and means for moving the turntable, substantially as described.

4. In an end dumping device, a lower sec tion of track, a movable platform traveling upon the lower section of track, a circular trackway upon the movable platform, a revoluble turntable having outer channel beams serving to journal wheels traveling upon the oirculartrackway, a centrally disposed for the revoluble turntable, means for moving the turntable, and an elevated section of track having its outer ends in register with tracks on the turntable, substantially as described.

5. In an end dumping device, a lower section of track, a movable platform traveling upon the lower section of track carrying a turntable, means for moving the turntable, an upper section of track having its supply and return tracks in register with tracks on the turntable for permitting filled dump cars to travel over the supply track onto the turn.-

table, and when dumped to travel on the re.-

turn track, substantially as described.
